Instrument

Doppler lidar system Stream Line (METEK GmbH, manufactured by Halo Photonics Ltd). The system consists of a solid-state pulsed laser emitting at infrared radiation and a heterodyne detector using fibre-optic technology, which is able to detect the frequency change in the received radiation due to the movement of the aerosol particles with the wind. The signal acquisition is performed continuously and autonomously in vertical mode with an adjustable temporal resolution down to 0.1 s and range resolution down to 18 m, and it also has full hemispheric scanning capability. With this system, it is possible to obtain vertical profiles of 3-Dimensional wind vectors at different altitudes within the whole atmospheric boundary layer.
